"She's Coming Home"

I listened to The Decca Stereo Anthology recently.  This afternoon, I was thinking about "She's Coming Home," and realized something about this section:

Oh, baby, baby, baby, I'll be good to you
If you would only try again to love me too
Our love was such a sweet and gentle thing
I threw our love away without a thought

Unlike the first verse, which exhibits an AABB rhyme scheme, this section has an AABC rhyme scheme.  That the last two lines don't rhyme illustrates in some way the singer/speaker's lack of thought.
